Ensure we don't end up with a null pointer dereferences by checking
for for allocation failures. Allocate by sizeof(*ptr) rather than
the type to fix checkpack warnings. Also merge multiple lines into
one line for the kmalloc call.

Detected by CoverityScan, CID#1422435 ("Dereference null return value")

OK, but could you change patch title to be less generic ?

Also, what tree is this patch targeting ?

# ls -l drivers/net/ieee802154/ca8210.c
ls: cannot access drivers/net/ieee802154/ca8210.c: No such file or
directory

This new driver is sitting in bluetooth-next right now for the next merge.
